The Good German

I don't know if this movie will win any awards. If it does, why? Anyway, it was nice to watch a 1940s movie in 1940s style filming. I didn't understand why it had to be b/w? Was there no color in the 40s? The storyline is creepy. There are a lot of charachters. Many of the US military, couple of Germans and Russians. In the whole movie, there is only a suggestion of who "The Good German" was. And he's the one hiding from the Americans and Russians in some dungeon. When he gets out, he's killed. Is this person the center of the movie's storyline? Considerably pathetic I'd say.
